What is a force?
What is friction?
What is "friction is a force that resists movement."
What is surface texture?
What is "Surface texture is the way an object feels".
What is a load?
What is "Load is the weight of the object you are trying to move."
What is force measured in?
What can friction create?
What is "friction can create heat and noise".
What is a disadvantage of friction?
What is "it can slow you down when you want to go fast."
Which would require more force - a backpack with one textbook or a backpack with four textbooks?

When a box is needed to be moved across the floor, what are the two forces that are acting on each other?
What is "the bottom of the box and the surface of the floor".
What is a slope?
What is "a slope is the change in height between two points."
What is a balanced force?
What is "balanced forces are when two forces of equal strength act in opposite directions."
How do you use force to change the direction of a moving object?
What is "when you change the direction the force is moving in, the direction of the object also changes."
What is an advantage of friction?
What is "An advantage of friction is that you will be able to walk and not slip." The friction between the surface of your shoes and the ground allows you to walk.
What happens if you want to move an object up a slope?
What is "the amount of force needed to move the object up the ramp will increase."
What is "there is no change in the motion of the object." The object stays completely still.
